Description

This PR adds an OSMO skill for Claude Code that enables natural-language interaction with the OSMO platform directly from the terminal.

What it does

The skill gives Claude contextual knowledge of the OSMO CLI, allowing it to autonomously run commands and interpret results on behalf of the user. It covers five core use cases:

• Check available resources — Lists accessible GPU pools and computes true effective availability (accounting for both quota limits and physical capacity). Automatically surfaces LOW priority submission opportunities when quota is
  exhausted but GPUs are physically idle.
• Generate and submit workflows — Generates valid OSMO workflow YAML from a natural-language description, referencing a built-in cookbook of 25+ real-world examples (SDG, RL training, GR00T fine-tuning, Cosmos, ROS2, remote dev
  environments, and more). Handles resource validation errors automatically by adjusting CPU/memory/storage to node capacity before resubmitting.
• List workflows — Displays recent workflow submissions with status, pool, and duration in a clean table with clear status symbols.
• Check workflow status and logs — Queries live status and fetches logs for running or completed workflows, with smart per-task log fetching for multi-task jobs. Offers to download output datasets on completion and translates
  Kubernetes scheduling events into plain language when a job is PENDING.
• Explain what a workflow does — Fetches the original workflow spec and summarizes it in plain language, covering what it runs, how it's configured, and what it produces.

Reference documentation

The skill includes three reference files Claude consults when needed:

• cookbook.md — Index of 25+ ready-to-use workflow YAML examples from the NVIDIA/OSMO GitHub repo
• workflow-patterns.md — Patterns for multi-task, parallel, pipelined, and Jinja-templated workflows
• advanced-patterns.md — Checkpointing, exit/retry behavior, and node exclusion

Issue #532
